Last Updated :
30 Oct, 2023
Lodash _.forOwn() method Iterates over the own keys of the given object and invokes iteratee for each property. The iteratee function is invoked with three arguments: (value, key, object). Iteratee function may exit iteration early by explicitly returning false.
Syntax:
_.forOwn( object, iteratee_function);
Parameters:
- object: This is the object to find in.
- iteratee_function: the function that is invoked per iteration.
Return Value:
This method returns an object.
Example 1: In this example, we are printing the key and value of the given object by the use of the lodash _forOwn() method.
javascript
const _ = require( 'lodash' );
let users = {
'a' : 1,
'b' : 2,
'c' : 3
};
_.forOwn(users, function (value, key) {
console.log(key, '=' , value);
});
|
Output:
a = 1
b = 2
c = 3
Example 2: In this example, we are printing the key and having greater than 2 value of the given object by the use of the lodash _forOwn() method.
javascript
const _ = require( 'lodash' );
let users = {
'a' : 1,
'b' : 2,
'c' : 3
};
_.forOwn(users, function (value, key) {
if (value > 2) {
console.log(key, value);
}
});
|
Output:
c 3
Note: This will not work in normal JavaScript because it requires the lodash library to be installed and can be installed using the following command:
npm install lodash
